Doubts about tax reform were raised late last week after details of the Senate's tax plans conflicted with the House GOP's proposed legislation.

The House is expected to bring a vote for its Tax Cut and Job Acts bill to the floor this week and it's likely the measure will pass. The proposed bill will pull between 225 and 230 Republican votes, according to estimates from The Hill. The bill needs 218 votes to pass. But the Senate plan, which would add $1.5 trillion to the country's deficit over 10 years and eliminate some popular deductions, may struggle to find support given the 60-seat threshold required for its passage.

2. -- Private-equity firm Roark Capital Group reportedly has made a $2.3 billion bid for Buffalo Wild Wings Inc. (BWLD) , just months after CEO Sally Smith announced she would retire by year-end amid pressure from activists.

Shares of Buffalo Wild Wings soared almost 28% to $150 in after-hours trading on Monday, Nov. 13, following a report about the bid from The Wall Street Journal.

Roark has a history of acquiring struggling casual dining chains and turning them around, as was the case with Arby's, which it bought in 2011, and Auntie Anne's Inc., which it purchased in 2010.

But some industry sources said Buffalo Wild Wings has enough livelihood to fend for itself, especially as investors were already optimistic about the prospects for a new CEO. The Minneapolis-based company beat Wall Street expectations last month with its third-quarter earnings report.

"We don't believe the Buffalo Wild Wings brand is dead. It still has good mindshare with consumers," said Jeremy Hamblin, a senior analyst at Dougherty & Co. "You can argue that most restaurant operators have struggled in recent years because of higher labor costs and lower traffic trends in casual dining."
